Title: Bonding of polyester material
Inventor: HIROKAWA ATSUSHI
IPC: B29C65/02
Filed: 1984-07-31
Abstract: PURPOSE:To bond polyester materials to each other easily without any adhesive, by subjecting the bonding surface of one of the materials to a low-temperature plasma treatment and subjecting that of the other material to a corona discharge treatment in bonding said materials by application of heat and pressure. CONSTITUTION:The bonding surface of one of polyester materials to be bonded is subjected to a low-temperature plasma treatment in argon, nitrogen or helium gas of 1X10<-3>-1Torr or a mixture thereof under conditions of a discharge power >=100W. The bonding surface of the other material is subjected to a corona discharge treatment in air, carbon dioxide gas, nitrogen gas, argon gas, oxygen gas, or a gaseous mixture thereof under conditions of a discharge power >=100W. Both the pretreated materials are bonded to each other by application of heat and pressure. In this way, they can be bonded to each other with a bonding strength sufficient for practical use.

Title: Clutch
Inventor: KISHI ICHIRO
IPC: F16D7/08
Filed: 1993-06-29
Abstract: PURPOSE:To provide stable operation by a method wherein the protrusion part of a clutch member is formed in the shape of a chevron in cross section in which the inclination angle on the top part side is lower than an inclination angle on the root side. CONSTITUTION:A clutch comprises a protrusion part 32 formed on the end face in an axial direction of an idling ring gear 31; a ball 33 engaged with the protrusion part 32; and a clutch spring brought into resilient contact with the ball 33 through a clutch disc. During cut off of transmission of a power by means of a clutch, the ball 33 is pressed out against a clutch spring by the ring gear 31. In this case, the ball 33 climbs up the slope of the protrusion part 32 of the ring gear 31 but between a force F1 by which the ring gear 31 pushes the ball 33 during the starting of climbing and a force F2 high enough to allow the ball 33 climbed by dy to climb up the slope of the protrusion part 32, a state of F2<F1 can be kept since the angle theta2 on the top part side of the slope of the protrusion part 32 is reduced to a value lower than an angle theta1 on the root side though the spring load of the clutch spring is increased. Thus, the ball 33 is caused to easily climb over the protrusion part 32 and stable clutch operation is provided.

Title: Electronic watthour meter
Inventor: SASANO KIYOSHI
IPC: G01R22/00
Filed: 1992-06-18
Abstract: PURPOSE:To measure wattage accurately by reducing pulse measurement time and excluding the influence of change in an instantaneous value of power and external accuracy loss factors simultaneously. CONSTITUTION:An integrator 11 integrates power data for a time specified by an integration time controller 10. A pulse interval arithmetic unit 12 obtains the pulse output interval corresponding to the output data of the integrator 11 and a pulse generator 9 successively generates pulses by the amount of pulse generation commands in stock at a specified interval thus outputting pulses at an equal interval for a period corresponding to the integration time of the integrator 11 and maintaining a certain accuracy determined by an integration time. Therefore, the accuracy is constant regardless of the measurement time. Reducing the measurement time and setting the integration time in the integration time controller 10 to a required accuracy achieves a quick and accurate measurement.

Title: Preventing circuit for generation of pop sound
Inventor: IZAWA KAORU
IPC: H03F1/00
Filed: 1980-11-13
Abstract: PURPOSE: To eliminate the generation of a pop sound by turning on a switch, provided to an output terminal, slowly after a power source is put to work.  
     CONSTITUTION: When a power switch 22 is turned on, a capacitor 20 is charged through a resistance 16. The charge potential of the capacitor 20 is applied to the base of a transistor (TR) 4 through a resistance 18. As a result, the emitter- side potential of the TR4 rises slowly to a value lower by the forward potential of the TR4. Consequently, a pop sound is generated in an amplifier 2 only before the TR4 rises, so that it will not appear at an output terminal 10.

Title: Magnet embedded rotor of rotating electric machine
Inventor: KATO TOSHIICHI
IPC: H02K1/22
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a magnet embedded rotor of a rotating electric machine capable of preventing erroneous insertion of a permanent magnet while evading complexity of manufacturing process and structure. SOLUTION: Radial direction sections forms of a magnet embedding hole 3 and a permanent magnet 4 are set as follows. In the magnetizing direction classified at odd-numbered order, a permanent magnet 4 can be inserted only in the odd-numbered magnet embedding hole 3 in the peripheral direction count, and in the even number magnetizing direction, a permanent magnet 4 can be inserted only in the magnet embedding hole 3 of an even number. By this constitution, an even-numbered permanent magnet 4 is not inserted into a magnet embedding hole 3 in the odd-numbered magnetizing direction. Similarly, it is also physically impossible that a permanent magnet 4 is inserted in a magnet embedding hole 3 of an even number in the odd-numbered magnetizing direction.  In a permanent magnet insertion work, a worker or a rotor can perform insertion work without confirming the insertion attitude of a permanent magnet one by one, so that the work is facilitated, erroneous insertion is not generated, and one kind of the permanent magnet 4 can be used.
